Checking the engine oil and
filter
[ We recommend that the engine oil
and filter be replaced by a HYUNDAI
authorised repairer.
[ If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.
[ To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used replace it according to the
maintenance schedule under severe
usage conditions.
[ The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
WARNING
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Used engine oil contains chemicals
that have caused cancer in laboratory
animals. Always protect your skin
by washing your hands thoroughly
with soap and warm water as soon as
possible after handling used oil.

Maintenance
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is filled
at the factory.
Check the antifreeze protection and
coolant concentration level at least once
a year, at the beginning of the winter
season, and before travelling to a colder
climate.

low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities.

It may cause water pump failure and

Checking the coolant level
OBC3090014
„Type A
„Type B
OBC3090061
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled
between [F (Full)] and [L (Low)] marked
on the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water.
Bring the level to [F(Full)], but do
not overfill. If frequent additions are
required, we recommend that the
system be inspected by a HYUNDAI
authorised repairer.

Maintenance
WARNING
OBC3090015
1. Check if the radiator cap label is
straight In front.
2. Make sure that the tiny protrusions
inside the radiator cap should be
securely interlocked.
Recommended engine coolant
[ When adding coolant, use only
distilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory. An
incorrect coolant mixture can result
in serious malfunction or engine
damage.
[ The engine in your vehicle has
aluminium engine parts and must be
protected by an phosphate based
ethylene-glycol coolant to prevent
corrosion and freezing.
[ DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
[ Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the
following table.

Changing the engine coolant
We recommend that coolant be changed
by an authorised HYUNDAI according to
the Maintenance Schedule.
NOTICE
Put a thick cloth or fabric around the
radiator cap before refilling the coolant
in order to prevent the coolant from
overflowing into engine parts such as
alternator.
WARNING
Do not use engine coolant or antifreeze
in the washer fluid reservoir.
Engine coolant can severely obscure
visibility when sprayed on the
windscreen and may cause loss of
vehicle control resulting in an accident.
Engine coolant may also cause damage
to paint and body trim.

Maintenance
Checking the brake/clutch fluid
level
OBC3090016R
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the left
or right side of the reservoir.
Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch fluid
contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition
associated with the wear of the brake
linings.
If the fluid level is excessively low,
we recommend that the system be
checked by a HYUNDAI authorised
repairer.

Maintenance
Filter inspection
The climate control air filter should be
replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it by
performing the following procedure,
and be careful to avoid damaging other
components.
Replace the filter according to the
Maintenance Schedule.
Filter replacement
OBC3050036R
1. Open the glove box.
OBC3090022R
2. Push in both sides of the glove box as
shown. This will ensure that the glove
box stopper pins will get released
from its holding location allowing the
glove box to hang.
OBC3N090013
3. Press and hold the lock on the left side
of the cover.
4. Pull out the cover.
5. Replace the climate control air filter.
6. Reassemble in the reverse order of
disassembly.
NOTICE
ODH073012
Install a new climate control air filter
in the correct direction with the
arrow symbol ( ) facing downwards,
otherwise, it may be noisy and the
effectiveness of the filter may be
reduced.
